TCF-142-RM Series Hardware Installation Guide

Fourth Edition, March 2015

Overview

Introduction

The TCF-142-RM series fiber converters are slide-in modules that can be installed in the NRack System’s rackmount chassis, such as the TRC-190 series. The slide-in module is equipped with a multiple interface circuit that can handle RS-232 or RS-422/485 serial interfaces, and multi-mode or single-mode fiber. The TCF-142-RM series slide-in modules are used to extend serial transmission distance up to 5 km (TCF-142-M-XX-RM, with multi-mode fiber) or up to 40 km (TCF-142-S-XX-RM, with single-mode fiber).

Why Convert Serial to Fiber?

Fiber communication not only extends the communication distance, but also provides many advantageous features. IMMUNITY FROM ELECTRICAL INTERFERENCE: Fiber is not affected by electromagnetic interference or radio frequency interference. It provides a clean communication path and is immune to cross-talk. INSULATION: Optical fiber is an insulator; the glass fiber eliminates the need for using electric currents as the communication medium. SECURITY: Fiber cannot be tapped by conventional electric means and is very difficult to tap into optically. Furthermore, radio and satellite communication signals can be captured easily for decoding. RELIABILITY & MAINTENANCE: Fiber is immune to adverse temperature and moisture conditions, does not corrode or lose its signal, and is not affected by short circuits, power surges, or static electricity.

No Configuration Required for Baudrate Settings

The TCF-142-RM slide-in modules work under any baudrate from 50 bps to 921.6 Kbps. The TCF-142-RM slide-in modules simply convert the signal back and forth between serial (RS-232, RS-422, or RS-485) and fiber, and since the TCF-142-RM slide-in modules do not need to interpret the signal, it does not need to know the baudrate of the transmitting device. For this reason, the TCF-142-RM slide-in modules do not have any DIP switches or jumpers for setting the baudrate.

Ring Mode

To allow one half-duplex serial device to communicate with multiple half-duplex devices connected to a fiber ring, you should configure the TCF-142-RM slide-in modules for “ring mode” by setting DIP switch “SW3” to the “On” position. The Tx port of a particular TCF-142-RM slide-in modules unit connects to the neighboring converter’s Rx port to form the ring. Note that when one node transmits a signal, the signal travels around the ring until it returns to the transmitting unit, which then blocks the signal. Users should ensure that the total fiber ring length is less than 100 km when using either single-mode models or multi-mode models.

Installation

The media converter slide-in module can be hot-swapped, which means the chassis doesn’t have to power off or be removed during installation. Align the slide-in module with the chassis installation slot so that the panel fastener screw is at the top of the module. Carefully slide the slide-in module into the slot while aligning the module’s circuit board with the installation guide. Ensure the slide-in module is firmly seated inside the chassis. Push in and rotate the attached panel fastener screw clockwise to secure the module to the chassis.

Switch Settings

There are 2 sets of DIP switches on the board. One set for fiber and another for the connector. Following are the settings for the 4 connector DIP switches.

Serial Connection Switch 1 Switch 2 RS-232 ON (default) ON (default) RS-422 ON OFF 2-wire RS-485 OFF ON 4-wire RS-485 OFF OFF 120Ω Terminator Switch 3 Enable ON Disable OFF (default) Fiber Mode Switch 4 Ring Mode ON Point to Point Mode OFF (default)

ATTENTION

For Fiber Ring Users: Before you plug the slide-in module into the chassis, make sure the DIP switch settings are correct before inserting the slide-in module into the chassis and connecting the serial and fiber cables. If the Rx LEDs of the converter glow continuously, remove the fiber cable and reconnect.

NOTE “Ring Mode” can only be used for half-duplex applications.
